LIFTING DEVICE FOR ROLLING MILLS.

LEE EoY JoHNsToN AND JAMES R. STANLEY, or ZANESVILLE, OHIO.

LI TING nEvIcE FOR ROLLING1VIILLS.

To all whom it may concern:

Be it known that we, LEE ROY JOHNSTON and J AMES R. STANLEY, citizens of the United States, residing at Zanesville, in the county of Muskingum and State of Ohio, have invented new and useful Improvements in Lifting Devices for Rolling-Mills, of which the following is a specification.

This invention relates to rolling mills and particularly to mills for rolling rods, bars and tubes or pipes.

The invention has for its object to dispose of the product as it emerges from between the rolls in a simple, eflicient and labor-saving manner and without undue manipulation.

A further object of the invention is to provide a construction whereby the products emerging from between the rolls will be antomatically intercepted at a predetermined point by a trip device, the actuation of which will set in motion mechanism whereby the product will be caused to move out of the way of the following rod, tube or other product.

A further object of the invention is to provide a simple and effective construction of parts whereby the product emerging from between the rolls will be disposed of gravitationally to move it out of the way of following products.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying'drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to When desired.

In the drawings,-Figure 1 is a side elevation of a device constructed in accordance with the invention. Fig. 2 isa top plan view. Fig. 3 is a transverse sectional view taken on the line 33 in Fig. 1.

Corresponding parts in the several figures are denoted by like characters of reference.

011 the floor 15 of the mill adjacent to that side of the rolls 16 where the product emerges is arranged an inclined platform 17,

Specification of Letters Patent.

Application filed April 10, 1915. Serial No. 20,486.

said platform being tilted transversely with respect to the rolls, and the said platform being adapted to receive the product that emerges from the rolls on its upper surface. The inclined platform 17 is sustained above the floor, level by means of uprights 18. Mounted on the platform 17 are a series of cover members 19, said cover members being preferably, but not necessarily, of arcuate shape, as shown, the purpose of said cover members being to temporarily retain upon the inclined platform the object or product emerging from between the rolls, means being provided whereby said cover members or obstructing members, as they may be properly termed, may be moved to a non-obstructing position, thereby permitting the product to slide gravitationally from the inclined platform. The cover members or obstructing members 19 are connected in series by a rod or connecting member 20.

In the embodiment of the invention shown. in the accompanying drawings, a standard or pedestal 21 is shown supporting a lever L, one arm of which, 23, is connected with one of the members 19; the other arm, 22, of said lever is connected by a link 24 with one arm of a lever 25 fulcrumed at 26, and the other arm of which is connected withthe armature 27 of an electro-magnet 28 contained in a circuit including conductors 29, 30, one of which is connected with a stationary member 31, and the other with a movable member 32 of a circuit closer.

The inclined platform 17 is interrupted or provided with a slot 33 which is located at a predetermined and. proper distance from the rolls. A trip member or treadle 34L fulcrumed at 35 has a portion thereof extended upwardly through the slot 33 so as to lie in the path of the product emerging from the rolls; said trip member also has an arm 36 which is connected by a link 37 with the movable member 32 of the circuit closer. A spring 38 is provided whereby the trip member 34lis normally held projected in the path of the object coming from the rolls.

From the foregoing description, taken in connection with the drawings hereto anneXed, the operation and advantages of this invention will be readily understood. The product or object coming from between the rolls will be received on the inclined platform on which it is temporarily retained by the cover members or obstructing members 19 which, being spaced apart, as shown, permit inspection of the product as it passes I 7 receiving position. Each object coming from between the rolls will thus be automatically disposed of and moved out of the path'of the succeeding objects Without the manipulation usually involved, thereby saving a considerable amount of labor and also preventing the bending or distorting of the objects Which frequently results from handling the same. hen a'number of finished products have been accumulated they may [be disposed of or moved out of the way in any convenient manner.

Having thus described the invention, what is claimed as new, is

1. In a rolling mill, the combination with a set of rolls, of a transversely inclined receiving platform, and a movably supported obstructing member.

2. In a rolling mill, the combination with a set of rolls, of a transversely inclined receiving platform, an obstructing member to retain an object emerging from the rolls on said platform, and means for moving said member to a non-obstructing position.

3. In a rolling mill, the combination with a set of rolls, of an inclined receiving platform, an obstructlng member to retain on said platform a product emerging from the rolls, and means for moving said member to a non-obstructing position including an electro-magnet, a circuit closer, and a trip device for actuating the circuit closer, said trip device being positioned in the path of a product emerging from the rolls.

4. In a rolling mill, the combination with a set of rolls, of an inclined receiving platform, an obstructing member to retain on said platform a product emerging from the rolls, a spring actuated trip device lying in the path of the product emerging from the rolls, and means actuated by said trip device whereby the obstructing member will be moved to a non-obstructing position.

5. In a rolling mill, a set of rolls, an inclined receiving platform supported above the floor level to receive products emerging from the rolls, said platform having an opening, a plurality of obstructing members supported adjacent to the platform to retain a product emerging from the rolls thereon, said obstructing members being connected in series, a spring actuated pivotally supported trip member having one end extended through the opening of the inclined platform in the path of a product emerging from the rolls, and means controlled by said trip member for moving the obstructing members to a non-obstructing position.

' In testimony whereof we affix our signatures in presence of two Witnesses.
